That forum link you posted had an Nvidia Tech Support guy responding to the original complaint within ten minutes! Try getting anybody from AMD to respond to a complaint at all...

Problem is that is the only response they gave...and it was almost a month ago..
Meh oh well I am back to the red come monday morning.

Also, with RC11 drivers there is a bug where your GPU usage goes awry when you switch from windowed mode with alt enter to full screen. Or should I say, if you go to windowed mode and switch back to full screen your GPU usage goes up. This only happens with RC11...it was weird, not sure how to explain it. Anyway, whoever did that crysis test, upgrade your drivers. 11.2 is horrible with GPU usage in crossfire, I had the same issues with RC11 at release.
Once I upgraded to 12.x everything was fine, really, the 12.x WHQL's are far better with GPU usage in crossfire. 12.4 WHQL has been really solid on my 7970 box as well.

Do you have both the multi GPU setups running. What clocks are you running the HD 7970's and GTX 680s at. Can you say which of the setups runs BF3 faster at 2560 x 1600 Ultra 4X MSAA , 7970 Crossfire or 680 SLI. can you tell both singleplayer and multiplayer. Also as they say at hardocp is the 680 SLI subjectively " smoother in BF3 " ?

Anyways . How are the drivers now for say skyrim? Was getting a lot of stuttering score I shipped out has that been fixed ?

Its not so clear cut. At maximum overclocks for both cards, they are even, and the 7970 wins many titles. If you compare stock clocks then yes, the 680 wins, but once you overclock the advantage goes away completely.

http://hardocp.com/article/2012/04/10/sapphire_hd_7970_oc_edition_video_card_review/

There you can see the 7970 OC basically decimate a stock 680. So don't fret too much. The 680 isn't by any means a bad card, it is awesome, but IMO it does not scale as well with overclocks as does the 7970.

Also: I see you joined the air force, lol. Why didn't you join a branch for real men? I kid wink.gif I was in the Marines side of the house and both Army and Marines are always jealous, if not completely hating on airmen because you guys have it GOOD compared to us. A LOT BETTER. I was stationed at Camp Lejeune and air force guys stationed there get substandard housing pay ... because apparently our facilities are run down compared to AF. lol.


That's what I have been hearing. Are the drivers doing good now? If I remember right one of my cards was a dud and couldn't get 1200. The other was flawless though.

Are the 680s doing decent at that and how are they sli vs crossfire?

By the way for the air force you're right lol. I did want to join the marines when I was in high school. Then I became wise wink.gif just kidding

I am doing diagnostic imaging as my job. Tough tech school here.

Ahh, I see. There must not have been an easy fix then. I've actually got my rig running pretty good right now on stock voltage with 12.4 beta. Problems arise when I start to clock beyond 1125MHz though and that's really the reason I got these cards. My 580 Lightnings could max every game too but I wanted better bench numbers that the 7970 gives at over 1200MHz. Not being able to adjust voltages without breaking all of my games is just frustrating as heck...

I'll probably try to get $500 if they are still hard to find at the time. $450 if they aren't. Supply and demand baby (of course I paid $600!!!) doh.gif

BF3 honestly felt the same speed on both setups. I use FRAPs to measure runtime framerates and the 2 setups are generally within 4-5 fps of each other. The max I was able to get on 680 sli stable was +100 offset, even at 135 offset I would get TDR's unless I used manual fan at ridiculously high settings (70%+...).

I think the issues with HardOCP is they run 3d surround. What is applicable to 3d surround is not applicable to single screen - I have had absolutely zero stutter or any such issues with single screen 2560 resolution. As far as eyefinity goes, it is really picky with the type of adapters you use, if you mix inputs improperly (1x dvi, 2x dp) you will get tearing and stuttering. I'm not sure how HardOCP has their testbed eyefinity setup. Nor do I care, I do not care about eyefinity or surround at ALL.

Anyway, with CF 7970 at 1125/1700, these games were faster on 7970 CF, 680 SLI at +100 offset:

Saints Row 3
Witcher 2 (a LOT faster)
Crysis 1/2/WH
Metro 2033 (a lot faster to my eyes)
Bulletstorm (a lot faster)
Just Cause 2 (slower on single gpu, faster on dual gpu)
Alan Wake (a lot faster on AMD)
Deus Ex: HR

Roughly the same, within 3-5 fps of each other:

Dragon Age 2
BF3
WoW
Kingdom of Amalur

Faster on 680:

Skryim (680 is just better in skyrim)
Dirt 3 (better on 680 but dirt 3 runs in the 100s of fps on anything )
Batman: AC (latest Batman: AC patch improved AMD framerates a TON in CF, they're about the same speed now....)
Batman: AA
GTA IV

The 680 is pretty awesome but the overclocking on my EVGA cards was not spectacular. I'll revisit it once good aftermarket cards are released, so far nearly every 680 doesn't allow you to manipulate voltage and have cheap VRM's.

Guys i need help, is it safe to increase memory voltage to say 1.65V?
And also, purple dots in Metro 2033, what could be, Vram or GPU core.
I just found video of same problem.
http://www.youtube.com/watch?v=_bXuUJQZMCc
But intensity is much lower on my card, exm. one in half hour.
If anyone can give couople of words on this, i will appreciate.

appreciate your feedback. So single screen dual Crossfire seems to favour HD 7970. If AMD could only get their Eyefinity drivers working stable . As a single card do you feel a 1.25 Ghz voltage OC HD 7970 is the better card against a 1.35 Ghz 680 OC (with turbo ) .
